Fruit Anthocyanins: Colorful Sensors of Molecular MilieuCurtright, Robert D.; Rynearson, James A .; Markwell, JohnProvides background and references as a starting point for the further exploration of anthocyanins.Curtright, Robert D.; Rynearson, James A .; Markwell, John J. Chem. Educ.1994, 71, 682.

Effect of Ionic Strength on Equilibrium ConstantsSeymour, M. D.; Fernando, QuintusInvolves the determination of the acid dissociation constant of bromcresol green by a spectrophotometric method; using a graphing calculator, each student can perform the laboratory work and obtain his own data set.Seymour, M. D.; Fernando, Quintus J. Chem. Educ.1977, 54, 225.

Teaching ionic equilibrium: Use of log chart transparenciesFreiser, Henry; Fernando, QuintusThe use of graphical methods brings the problem of significance of various terms in complicated expressions into proper focus. Furthermore, a pictorial representation permits the student to see at a glance how the concentrations of various species in a system at equilibrium change with conditions.Freiser, Henry; Fernando, Quintus J. Chem. Educ.1965, 42, 35.
